Describe the Bug

Starting from 2.0 running astro build causes this warning when using sourcemaps. I haven't tested it thoroughly, but it seems like this is just a warning and sourcemaps for my code are still there.

Warning:

09:45:56 PM [build] Building static entrypoints...
Sourcemap is likely to be incorrect: a plugin (astro:scanner) was used to transform files, but didn't generate a sourcemap for the transformation. Consult the plugin documentation for help

stackblitz is just a fork of default astro template where I enabled sourcemaps and ran build:

hey, didn't mean to rain on your parade, but :)

while the simplest possible case (the stackblizt link that I created) was fixed, I still see those errors in my production website

here's an example of latest (2.0.10) build that produces the same warnings https://github.com/JLarky/qgp.app/actions/runs/4153799688/jobs/7185669325

Seems to be caused by

astro/packages/astro/src/content/vite-plugin-content-imports.ts

Line 130 in 8b7cb64

return { code: escapeViteEnvReferences(code) };

That might need magic-string to replace and generate a new sourcemap.
